Yes we know that the untethered jailbreak for the A5-based iPhone 4S and iPad 2 is close to being released, but thanks to a recent post by the iPhone Dev-Team, it looks like the hour is nearly upon us. According to their post, the Corona A5 jailbreak for the iPhone 4S and iPad 2 are close to being released, especially since the team has overcome the technical hurdles associated with the underlying technique that was required to achieve the jailbreak.
It seems that all that remains now is a couple of bug fixes before a general release is made available for the public, and should work for the iPhone 4S running on iOS 5.0 (9A334), 5.0.1 (9A405) and 5.0.1 (9A406), and the iPad 2 running on iOS 5.0.1 (9A405). According to the Dev-Team, the jailbreak GUI will remain streamlined and a command-line interface will also be provided for users who wish to run their own scripts for further customization. Ultimately the Dev-Team is also hoping to see the Corona A5 jailbreak integrated into redsn0w in the future.
The team has also warned users that since the Corona A5 jailbreak has never been done before, there could be unforeseen problems when released to the public and that backing up all your data, such as contacts, photos, music, etc, should be done before attempting the jailbreak.
